where \(h\)  is a Yukawa coupling and \(g\)  is a non-Abelian gauge coupling. In the absence of non-Abelian couplings the theory with scalars and fermions is known to have a positive term \(c_h h^2\)  in front of the \(\ln |X|^2\) . An opposite choice is now taken in eq. (3.1) in [1]} where the constant \(\tilde{\zeta }= -{c\over M^2}\)  is positive, i.e. \(c\)  in eq. (REF ) here is negative.
